II. automation component communication and renewal
Fig. 3 illustrates example communication and the Reconfigurations 300 that can implement between automation component 200.In this exemplary configuration, automation component 200a can be configured to realize request-response (poll) communication 302, in order to information is moved to polling device or shifted value onto 200a equipment for 200b equipment from 200b equipment.For example, automation component 200a can represent field panel, FPX or another full-function device.Similarly, automation component 200b can represent TEC, FLNX, global function or simplify function device, wireless actuator or can be at any other wired or wireless equipment of BAS 100 interior operations.In addition, automation component 200a, 200b can be exercisable in for example mesh network or subnet 118a.
A. request-response (poll) communication
Fig. 4 illustrates polling communication algorithm 400 or the method that can for example realize between automation component 200a, 200b.At square frame 402 places, can be that the automation component 200a of field panel or other full-function device can the generation value change (COV) request message and send it in BAS 100 and/or the one or more automation component 200b that operate in the independent FLN that consists of BAS 100.Whether the COV request message can ask or order automation component 200b to indicate local detected value, reception value, parameter or measurement result to be modified or change above predefine the report limit, for example the COV limit.
At square frame 404 places, automation component 200b receives the COV request message.For example, if automation component 200b automatically receives last COV request message and plays the new value that detects or receive the variation of expression value, then at square frame 406 places, automation component 200b can generate be used to the COV acknowledge message that is sent to automation component 200a.Perhaps, if automation component 200b does not detect or receive the new value that the expression value changes, then at square frame 408 places, automation component 200b can generate be used to the COV acknowledge message of negating that is sent to automation component 200a.
At square frame 410 places, if the COV acknowledge message that is provided by automation component 200b successfully is provided automation component 200a, then automation component 200a can generate and send for the affirmation COV request message of answering automation component 200b.
At square frame 412 places, automation component 200b knows that in response to the affirmation COV request message that is provided by automation component 200a OCV successfully is sent to equipment 200a and removes the COV of those reports, and affirmation COV request acknowledge message is provided.Behind square frame 412, the communication of algorithms 400 can be restarted and can be carried out poll to another wireless device or the automation component in the BAS 100.Be understood that can be in wired or wireless BAS 100 the realization example communication of algorithms 400.
B. pushing-type communication
Fig. 5 illustrates the replacement communication of algorithms 500 or the method that can for example realize between automation component 200a, 200b.Can adopt example communication method 500 at the BAS 100 that is configured to for the mixed communication that utilizes wired and radio communication.
At square frame 502 places, it can be the new or changing value that the automation component 200b of for example full-function device, FLNX and/or TEC will check its input and output.If comparing with the value of final report (FR), new value changes the predefined amount that surpasses, then will be at this variable of next time COV communication report.
At square frame 504 places, automation component 200b will to check whether wait for that report value changes (COV) by the regular intervals of time of inner COV report interval establishment or according to the needs inspection of internal algorithm.If so, then automation component 200b establishment is comprised all queuings (queued) COV value promotion COV message and send it to automation component 200a.At square frame 506 places, automation component 200a is receiving and is understanding in the situation of this message and can confirm that response respond automation component 200b with promoting COV, perhaps, at square frame 508 places, respond in affirmation (NAK) and the error code do not understood in the situation of this message with negating.When receiving, at square frame 510 places, automation component 200b removes the COV state.At square frame 512 places, automation component 200b can turn back to its normal running, until till the next time inspection to new value.
Automation component 200a processes the COV of those queuings in the internal database of automation component 200a now, and can be alternatively as the accompanying drawing of Fig. 1 and explanation are defined with those value reportings to miscellaneous equipment.
If automation component 200b is actually the hardwired device with external wireless network interface, such as the TEC with FLNX configuration, then FLNX need to carry out poll to TEC for COV, and hold it in the FLNX when occurring to the communication of automation component 200a.In addition, FLNX will need as the algorithm of Fig. 4 is defined the COV from TEC to be confirmed.
If automation component 200a is the hardwired device with external wireless network interface, such as the field panel with FPX, then FPX will need to move and have be used to the buffer of the COV that is pushed and be used in the COV queuing of field panel.Field panel will be carried out poll so that COV is received in the database of automation component 200a to FPX according to the algorithm of Fig. 4.
In this configuration, the communication of algorithms 500 allow from one or more automation component 200b until 200a equipment and from 200a equipment to as defined other system component of Fig. 1 is collected and promotion COV related news.By with each automation component 200b is carried out poll promotes COV on the contrary until automation component 200a uses less wireless bandwidth and shortened system's end-to-end delay.
If automation component 200b has done the time period (such as definition of internal variable) that prolongs in steady state operation in without any the situation of COV, automation component 200b will communicate by letter with automation component 200a, so that automation component 200a knows that automation component 200b is still in operation.If do not receive message from automation component 200b in the time period of automation component 200a defined built-in variable in being longer than automation component 200b, then automation component 200a will report with automation component 200b communicate by letter lose.
The communication of algorithms 500 can also be configured to solve and process for example difficult communication between automation component 200a, the 200b or mistake.For example, if can not transmit the affirmation of COV polling request or its reception automation component that does not obtain expecting, then algorithm 500 can be configured to recover from communication failure.Communication recovery can comprise repeated communications trial pre-determined number (for example attempting for ten times).Similarly, unsuccessful if the communication that repeats is attempted, then communication recovery may be overtime and can be again attempted afterwards this program in predetermined delay (for example per 30 minutes).In addition, during the time period that can not communicate, still during rebuilding, communication assembles and storage COV related news.
Be understood that various changes and modification to present preferred embodiment described herein will be apparent for a person skilled in the art.For example, can according to system requirements, performance requirement, and other expectation ability with any known way the element of these configurations is arranged and is exchanged.Based on instruction provided by the present invention and open, and in the situation that does not reduce its intended advantages disclosed herein, can carry out change and the modification thoroughly understood.Therefore, be intended that the claim of enclosing and contain this type of change and modification.
